ABSTRACT:
An instantaneously acting fall preventing device comprises a casing containing a locking mechanism, in the form of a series of rings which are adapted to co-operate with a retaining cord, and a connecting element for attachment to a harness or safety belt. The upper ring of the series of rings is provided with a lever which passes through a wall of the casing and extends into a guidance member for the connecting element. When the device is in the unlocked position, the lever is held against an abutment in the guidance member and said lever moves away from the abutment in the event of a fall to permit the rings to engage the cord and lock the device.
